BOTANICAL CLASSIFICATION

Prunus persica var. nucipersica.

VARIETY DENOMINATION

‘NECTAVANPI’.

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Prunus persica var. nucipersica yellow nectarine tree, which has been given the denomination ‘NECTAVANPI’. This tree, named ‘NECTAVANPI’, produces clingstone fruits of good eating quality for fresh market in end of August, beginning of September in the 66—Pyrénées-Orientales departement—France. Contrast is made to ‘Nectalady’ (U.S. Plant Pat. No. 17,580), ‘Maillardou’ Bonbon® (non-patented), ‘Maillarboom’ Bigboum® (non-patented) and ‘Red Jim’ (patent status unknown) yellow nectarine trees, standard varieties, for reliable description. ‘NECTAVANPI’ is a promising candidate for commercial success in that it has an evenness of maturity, and produces regular fruits in large quantity and with a high productivity. It was chosen because of its hardiness and fruit lifetime before and after harvest, and because of its aromatic semi-sweet taste.

ORIGIN OF THE VARIETY

‘NECTAVANPI’ nectarine tree originated in a cultivated area of the south of France, in the 66—Pyrénées-Orientales departement—France where it was tested. This place is under a Mediterranean climate (a temperate area), on the Mediterranean coastline. Winters are gentle and summers warm and dry. The amount of days with temperatures below 7° Celsius can vary between 600 and 1200 hours per year. The place is sunny, with 2400 to 2800 hours of sunny days per year on average. The prevailing wind is called ‘Tramontagne’: it dries the air, clears the sky from clouds, but its intensity can be strong and affect the harvest, fruit quantity and/or quality.

Marine moisture does not affect the place. Precipitations are irregular through the year and from one year to another. The amount of rainy days does not exceed 80 days per year, and are mostly in Spring and Autumn. In May and October, very intense precipitations occasionally happen. Summer is dry with a few thunderstorms.

The ‘NECTAVANPI’ variety was selected from controlled crosses between the ‘Maillardou’ Bonbon® (non-patented) yellow nectarine tree (female parent) the ‘Maillarboom’ Bigboum® (non-patented) yellow nectarine tree (male parent). ‘NECTAVANPI’ was provisionally designated, tested and genetically identified by a genetic profile, as 03.22.124 NJ ASF 0413 and was registered at the Official Catalogue of the Agriculture Ministry of the French Republic on Dec. 1, 2008 under number 1028952. It was obtained by hybridizing and propagated by grafting on ‘Franc Inra Montclar®’ (non-patented), ‘Cadaman’ (patent status unknown) or ‘INRA GF 677’ (patent status unknown) rootstock trees. It has been determined to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of the rootstock varieties set forth above on the scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree and the fruit were transmitted. The plant was reproduced asexually by us in Les Régalines, Route d'Alenya, La Prade de Mousseillous, 66200 ELNE, Pyrénées-Orientales, France.

SUMMARY OF THE VARIETY

The new and distinct variety of nectarine tree blooms in March at Perpignan in the Pyrénées-Orientales departement, France. More particularly, it generally blooms approximately between March 2^(nd) and March 13^(th), approximately at the same time than ‘Nectalady’ (U.S. Plant Pat. No. 17,580).

The first fruit of ‘NECTAVANPI’ ripens at the end of August, generally about 3 to 4 days before ‘Nectalady’ (U.S. Plant Pat. No. 17,580). Comparatively, the male parent of the variety, ‘Maillarboom’ Bigboum® (non-patented), ripens during the two first weeks of July. More particularly, it approximately ripens between August 25^(th) and September 4^(th) under normal climatic conditions.

DETAILED BOTANICAL DESCRIPTION

The tree, flowers, and fruit may vary in slight detail due to variations in soil type, cultural practices, and climatic condition.

Trees are of medium stature, half-standing in a semi-spread to semi-upright out aspect. The anthocyanic coloration of the flowering shoot is present excluding brushwood side away from sun. Flowering begins semi-early in springtime. The type of flower is showy with generally medium to large petals of light to medium pink color. Leaf glands are present and reniform. Time of maturity for consumption is late.

The fruit flesh is yellow with generally no red pigmentation. Fruit skin color features a bright red blush on an orange ground color. Fruit taste is semi-sweet.

The ‘NECTAVANPI’ variety blooms almost at the same time and ripens 4 days before the ‘Nectalady’ variety (U.S. Plant Pat. No. 17,580). However, ‘NECTAVANPI’ fruits are bigger than ‘Nectalady’ fruits, and clearly more appealing, especially because of a smoother skin surface. ‘NECTAVANPI’ fruit skin is also less sensitive to damages caused by climatic conditions, especially rains, and to conservation diseases than ‘Nectalady’ fruit skin.

The ‘NECTAVANPI’ variety generally ripens 8 to 10 days after the ‘Red Jim’ (patent status unknown) variety. However, ‘NECTAVANPI’ fruits are more appealing because of their larger blush coverage. ‘Red Jim’ fruits have a balanced taste instead of semi-sweet taste for ‘NECTAVANPI’ fruits.

The new variety female parent, which is ‘Maillardou’ Bonbon® (non-patented), also has a late date of maturity, but ripens later than the new variety. ‘Maillardou’ fruits are medium in size, very round, of orange-red color and have a very sweet semi-sweet taste.

The new variety male parent, which is ‘Maillarboom’ Bigboum® (non-patented), has a semi-early date of maturity, thus comparatively ripens earlier than the new variety. ‘Maillarboom’ fruits are very appealing and of large size, entirely colored with a bright red blush, but the variety does not produce a large amount of pollen.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of nectarine tree, the following was observed on trees in their fourth growing season under the ecological conditions prevailing at the orchards located near the town of Elne, Pyrénées-Orientales departement, France. All observations have been done on rootstock cultivars. Used rootstocks were ‘Franc Inra Montclar®’ (non-patented) trees or ‘Cadaman’ (patent status unknown) trees or ‘INRA GF 677’ (patent status unknown) trees. All major color code designations are by reference to The R.H.S. Color Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

-   Tree: -   Size:     -   -   Generally.—Considered large. The tree size the first year             was approximately 250 cm. The tree was pruned during each             following dormant season to a height of approximately             250 cm. Current season shoots growth could reach 60 to             80 cm. The tree size from the second year (second and next             years) reached a final height of 310 to 330 cm with current             season shoots length comprised.         -   Spread.—Approximately 100 cm with a cylindrical shape. The             whole orchard was oriented to a central leader organization,             with tree lines spaced of 4.0 meters and trees spaced of 1.0             meter in a same tree line. As a result, tree spread was             about 100 cm and the orchard contained 2500 trees by             hectare.         -   Vigour.—Considered average.         -   Productivity.—Very productive. Fruit set is spaced by             thinning to develop the remaining fruit into the desired             market sized fruit. The number of the fruit set varies with             the prevailing climatic conditions, and cultural practices             employed during the bloom period, and is therefore not             distinctive of the present variety.         -   Bearer.—Very regular. Fruit set was generally heavy during             the years of observation and thinning of 1 fruit on 3 was             generally necessary every year.         -   Form.—The ‘NECTAVANPI’ variety has naturally a semi-spread             to semi-upright shape.         -   Density.—Considered dense.         -   Hardiness.—The present tree was grown and evaluated in             France. The variety appeared to be hardy under typical             central Pyrénées-Orientales departement climatic conditions             and was partly selected because of its hardiness.             Experimentations on different sites with winter chilling             requirement comprised between 350 and 1200 hours showed a             good behavior of the tree in all cases. Ascertained             temperatures as low as −12 degrees Celsius in winter caused             no damages to the tree. The tree was also very resistant to             frosty springtime weather. -   Trunk:     -   -   Diameter.—Approximately between 6.0 and 7.5 cm in diameter             when measured at a distance of approximately 30 cm above the             soil level.         -   Bark texture.—Considered rough.         -   Lenticels.—Numerous lenticels are present. The lenticels             range in size from approximately 0.5 to 0.7 cm in width, and             from 0.15 to 0.2 cm in height.         -   Lenticel color.—The outside of lenticels has a silver-grey             color (RHS Grey 201 C), whereas the inside is considered             brown (RHS Greyed Orange 166 B).         -   Bark coloration.—The bark has a silver-grey color (varying             from RHS Grey 201 C to RHS Black 202 C) -   Branches:     -   -   Size.—Mature branches as well as current season shoots are             medium for the variety.         -   Diameter.—Average as compared to other nectarine varieties.             The current season shoots have a diameter from 5.0 to 6.0             millimeters, and branches of trees have a diameter comprised             between 18.0 and 25.0 millimeters.         -   Surface texture.—Average, several years old wood has no             furrowed appearance.         -   Crotch angles.—Primary branches are considered variable, but             the crotch angles are generally between 60 and 80 degrees             from the horizontal axis. This particular characteristic is             not considered distinctive of the variety, however. -   Current season shoots:     -   -   Surface texture.—Substantially glabrous.         -   Internode length.—Generally 20.0 to 32.0 millimeters.         -   Color of mature branches.—Medium brown (RHS Grey Brown 199 A             to B). -   Current seasons shoots:     -   -   Color.—The color of new shoot tips is considered a light             yellow green (varying from RHS Yellow Green 144 A to RHS             Yellow Green 144 C) on lower part of new shoot tips, whereas             the upper part is colored in purple brown to red brown             (varying from RHS Greyed Purple Group 187 A to B to RHS             Greyed Red 182 A). -   Leaves:     -   -   Size.—Considered medium to large for the species. The ratio             leaf length/leaf width is above 4.         -   Leaf length.—Approximately 140 to 200 millimeters with             petiole.         -   Leaf width.—Approximately 35 to 48 millimeters.         -   Leaf base shape.—Concave.         -   Leaf form.—Lanceolate.         -   Leaf tip form.—Small and acuminate. -   Leaf color:     -   -   Upper leaf surface.—Dark Green (RHS Green 137 A).         -   Lower surface.—Medium Green (RHS Green 137 B to 137 C).         -   Leaf texture.—Smooth and glabrous.         -   Leaf venation.—Pinnately veined. -   Mid-vein:     -   -   Color.—Generally a Light yellow green (RHS Yellow Green 145             D to 145 C).         -   Leaf margins.—Slightly undulating.         -   Form.—Considered slightly dentate.         -   Uniformity.—Leaves are isolated or grouped by 2 or 3. In             this last case, one leaf of normal size is found with one or             two smaller leaves (at least 50% smaller). -   Leaf petioles:     -   -   Size.—Considered medium.         -   Length.—About 8.0 to 12.0 mm.         -   Diameter.—About 1.5 mm.         -   Color.—Light yellow green (RHS Yellow Green 144 D to 144 C). -   Leaf glands:     -   -   Size.—Considered medium, about 1.5 mm.         -   Number.—Generally 2 or 3, but up to 5 leaf glands can be             found.         -   Type.—Reniform.         -   Color.—On young leaves, leaf glands color is considered a             pale green (RHS Green 144 B to A). On older leaves, leaf             glands color turn to a dark brown (RHS Grey Brown 199 A to             199 B). -   Leaf stipules:     -   -   Generally.—No leaf stipules were observed. But as seen in             the characteristic relative to the leaves uniformity, it is             possible to find leaves by groups of 2 or 3, with a             normal-size leaf and smaller ones. -   Flowers: -   Flower buds:     -   -   Generally.—At pre-floral stage of development, the floral             buds are conic in form with a round tip. Their form is             evolving until blooming, with variables dimensions. Just             before blooming, floral buds are approximately 11.0             millimeters wide and approximately 20.0 millimeters long. -   Flower buds:     -   -   Color.—This characteristic is dependent upon the proximity             to bloom. At pre-floral stage of development, the bottom of             the flowers buds, formed by sepals, is of purple-brown color             (Generally RHS Greyed Purple 183 A to C); the corolla,             formed by petals, is generally of medium pink color (varying             from RHS Red Purple 69 B to C to RHS Red Purple 65 A to C).             Petals color shows an evolution until the end of flowering.             The buds are considered hardy under typical central             Pyrénées-Orientales departement climatic conditions.         -   Hardiness.—No winter injury was noted during the last             several years of evaluation in the central Pyrénées             Orientales departement, with winter temperatures as low as             −10 degrees Celsius in January. The current variety has not             been intentionally subjected to drought or heat stress, but             the variety showed a very good resistance in orchard to             temperatures up to 42 degrees Celsius with an average             temperature between 28 and 30 degrees Celsius during 3 weeks             in summer.         -   Date of bloom.—Generally early March. The first bloom was             observed on Mar. 5, 2001.         -   Blooming time.—Considered medium in relative comparison to             other commercial nectarine cultivars grown in the             Pyrénées-Orientales departement, France. The date of full             bloom is observed in March, more particularly between March             2^(nd) and March 13^(th). The date of bloom varies slightly             with climatic conditions and cultural practices. Last             observed blooming times were from Mar. 10, 2006 to Mar. 20,             2006, then from Mar. 4, 2007 to Mar. 16, 2007, then from             Feb. 22, 2008 to March 3, 2008, then from Mar. 2, 2009 to             Mar. 13, 2009.         -   Duration of bloom.—Approximately 12 days. This             characteristic varies slightly with the prevailing climatic             conditions.         -   Flower type.—The variety is considered to have showy type             flowers.         -   Flower size.—Considered medium to large.

Filaments length is generally longer             or equal to pistil's length.         -   Color.—Considered light pink (varying from RHS Red Purple 62             C to D) darkening over time. -   Pistil:     -   -   Number.—Usually 1.         -   Generally.—Medium in size.         -   Length.—Approximately 16.0 to 19.0 millimeters including the             ovary; Generally approximately equal or smaller than             filament's length.         -   Color.—Considered a very pale green (varying from RHS Yellow             Green 150 D Group to RHS Yellow Green 151 D Group).         -   Surface texture.—The variety has a glabrous pistil. -   Fruit:     -   -   Maturity when described.—Very firm ripe condition (shipping             ripe).         -   Date of first picking.—Aug. 25, 2001. The picking generally             occurs between August 25^(th) and September 4^(th) under             normal climatic conditions. The date of harvest varies             slightly with the prevailing climatic conditions.         -   Date of last picking.—Sep. 4, 2001. Picking can generally be             achieved with only 2 harvests within approximately 12 days.             Last known picking times were from Aug. 25, 2005 to Sep. 4,             2005, then from Aug. 26, 2006 to Sep. 4, 2006, then from             Aug. 24, 2007 to Aug. 31, 2007, then from Aug. 23, 2008 to             Sep. 2, 2008, then from Aug. 31, 2009 to Sep. 11, 2009. -   Size: Generally.

The red blush covers between             50% and 90% of the fruit skin surface.         -   Ground color.—Orange (Varying from RHS Orange Red N 34 A to             RHS Orange N 25 A to C) on about 10% to 50% of the fruit             skin surface.         -   Fruit stem.—Medium in length, approximately 5.0 millimeters.         -   Diameter.—Approximately 4.0 millimeters.         -   Color.—Pale green (RHS Yellow Green 145A to 145 B). -   Flesh:     -   -   Ripens.—Very evenly, homogenous, long shelf-life of the             fruit.         -   Texture.—Very firm, very dense, juicy at harvest maturity             stage.         -   Fibers.—No fibers.         -   Aroma.—Pronounced.         -   Eating quality.—Considered very good and aromatic.         -   Flavor.—Considered semi-sweet. The Brix is generally             superior to 13.0 degrees. Acidity is comprised between 6 and             9 meq/100 ml. The flavor is considered aromatic. The flesh             is juicy.         -   Juice.—Very juicy at complete maturity.         -   Brix.—Generally superior to 13.0 degrees. This             characteristic varies slightly with the number of fruit per             tree, the prevailing cultural practices and the surrounding             climatic conditions.         -   Flesh color.—Generally Yellow Orange (RHS Yellow Orange 16 B             to C). There is generally no red pigmentation under the             skin. However, the flesh is red inside the stone cavity and             around the stone cavity, forming a star-shape of about 1 cm             of diameter. -   Stone:     -   -   Type.—Clingstone.         -   Size.—Considered medium to large for the variety.         -   Length.—Approximately 30 to 33.0 millimeters.         -   Width.—Approximately 22 to 24.0 millimeters.         -   Diameter.—Approximately 17.0 to 19.0 millimeters.         -   Form.—Elliptic.         -   Base.—Straight. -   Apex:     -   -   Shape.—The stone apex has a small sharp tip.         -   Stone cavity.—Considered medium to large-sized, with an             elliptic-form. Stone cavity's dimensions correspond to the             stone's dimensions. -   Stone surface:     -   -   Surface texture.—The pit is transversely furrowed on its             entire surface. Furrows are more pronounced toward the apex.             The stone is pitted toward the base. Relief is generally             prominent and present basally.         -   Ridges.—The surface texture is generally characterized by             more prominent ridges along the ventral edges and is more             prominent at the apical tip. -   Ventral edge:     -   -   Width.—Considered small to medium, and having a dimension of             approximately 2.0 millimeters at mid-suture. -   Dorsal edge:     -   -   Shape.—Grooved.         -   Stone color.—The color of the dry stone is generally a light             orange-brown (RHS Greyed Orange 166 A to D).         -   Tendency to split.—Splitting is generally absent. -   Kernel:     -   -   Size.—The kernel is considered medium.         -   Length.—About 20.0 millimeters.         -   Width.—About 12.0 millimeters.         -   Thickness.—About 3.0 to 4.0 millimeters.         -   Form.—Considered flattened and elliptic.         -   Pellicle.—Slightly pubescent.         -   Color.—The kernel skin is brown-orange (RHS Greyed Orange             167 C) with darker brown-orange streaks (RHS Greyed Orange             166 C). The almond is cream-white (RHS Orange White 159 D).             The kernel and its embryo are mature at the time of fruit             maturity.         -   Use.—The subject variety ‘NECTAVANPI’ is considered to be a             nectarine tree of the late season of maturity, which             produces aromatic semi-sweet fruit with a brix higher than             13 degrees. Fruits are excellent for uncooked consumption,             crunchy or at full maturity. Due to their flesh quality,             firmness and density, they can also be commercialized as             4^(th) range product (packed fruit or fruit in bags for             example). Fruits are also useful for both local and very             long distance shipping because they have a long shelf life             after harvesting, up to 1 month.         -   Keeping quality.—Remarkable. Fruits stayed a little more             than one week on tree before harvest and then, has stored             well more than 4 weeks after harvest at 2.0 degree Celsius.             They have a slow maturation and a long shelf life both on             the tree after growth completion and after harvesting             without alteration.         -   Shipping quality.—Considered very good. Fruits of the new             nectarine variety showed minimal bruising of the flesh or             skin damage after being subjected to normal harvesting and             packing procedures. Its resistance to handling during             harvest and packing and its long shelf life without             alteration after harvest easily permit 3 to 4 weeks shipping             at 2 degrees Celsius.         -   Resistance to insects and disease.—No particular             susceptibilities were noted. Under our climatic conditions,             favourable to powdery mildew, and with few treatments, the             present variety has not been shown to be very sensitive to             powdery mildew, or conservation diseases and decay due to             its thick and strong skin. No bacteriostatic substances were             applied, and no symptom was observed. -   Although the new variety of nectarine tree possesses the described     characteristics when grown under the ecological conditions     prevailing near the town of Elne, France, it should be understood     that variations of the usual magnitude and characteristics incident     to changes in growing conditions, fertilization, pruning, pest     control and horticultural management are to be expected.
